Thank you, I picked this old drive that I had remove because I suspected it was flaky so I could see what negative result look like. Planning on replacing all my drives with some new HGST 3tb NAS drives soon. thanks!

I ran a preclear on a drive I just replaced and do not trust in an attempt to understand the preclear results so I can test all drives I use moving forward. Can you help me understand these results?
